This invention appertains to new and useful improvements in razors andthe principal object of the invention is'to provide a razor blade whichwill eliminate the creation of .6 vacuum which occurs duringtheoperation,

of shaving, as when the blade is held close to the face. i

Another important object of the invention isto provide a razor bladewhich is perforated to increase the flexibility thereof which isdesirable when honing or stroppmg.

These and other important objects and advantages of the invention willbecome a parent to the reader of the following speci cation.

In the drawing Figure 1 represents a perspective vlew of the improvedrazor. Fig. 2 represents a vertical sectional View taken substantiallyon line 2-2 of Fig. 12,

Referring to the drawing wherein like numerals designate like parts, itcan be seen that numeral 5 represent the usual handle for receiving theblade 6, he blade 6 being prov-ided with the usual shank'7 andfingerengageable extension 8 which is pivotally connected to the handle 5 asat '9.

The blade is of the concave type and in carrying out the invention, itcan be observed in Fig. 1-, that the thick back side 10 of the blade isthe starting point for a plurality of grooves 11 extending inwardly onthe blade and on opposite sides thereof to terminate at apertures 12which extend through the blade midway between the longitudinal edgesthereof. These openings 12 are arranged on a line passing longitudinallythrough the center of the blade and as is clearly shown in Fig. 1additional openings 13 are provided through the blade at points betweenthe grooves 11 and more toward the thickened back portions 10 and theopenings 12.

It can also be seen, that the grooves 11 taper inwardly so as to mergewith the face of the blade. Manifestly, in the act of shaving air caneasily enter by way of the openings 12 and grooves 11 aswell as theopening 13 tion, in that they add to the flexibilit of the blade so thatthe same will easil ex and flatten out on the hone or strop w en in theact of honing or stropping the razor.

7 While the foregoing specification sets forth 65 the invention inspecific terms, it is to be understood that numerous changes the shape,size and materials may be resorted to without departing from the spiritand scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is A razor ofthe character described comprising a blade having a thickened edgeportion, said blade being provided with inwardly ex- 65 tending groovesextending inwardly from the thickened edge portion, said blade beingrovided with openings at the inner ends 0 the said grooves. v
